Lift travel is not consistent across the range and assuming it is will cost a splitter. A 992 with the factory front-axle lift raises about 40 mm; the GT3 and GT3 RS system raises about 30 mm. Both are speed-limited and retract on their own once the car is moving. On a GT3 the front overhang is longer and the splitter sits further forward than on a Carrera, so the number that matters is the distance from splitter edge to first contact on the ramp, not published ground clearance. A Carrera GT has no lift at all; it loads on a level deck, extended ramps, with a spotter at the nose.

Rear weight bias on the rear-engined cars sits around 39/61, which changes where the car is positioned on the deck and how it behaves under braking on a wet steel ramp. Axle loads are worked out before the car moves. Cup 2 and Cup 2 R tires are common on the GT cars and are not designed to be stored or driven near freezing; they take a flat spot on a cold overnight transit and need to be rolled and warmed gradually at the far end. PCCB discs give less cold bite than steel at load-in speed.

Taycan and Macan Electric travel at a specified state of charge. Securement is soft loop over the tire at four points, with nothing bearing on the sill, the plastic undertray, or the front lip.
